Station Maps for the Occultation by
NORTH and SOUTH
at Friday, 2008 February 08 (~ 17:55 UT)
This occultation was predicted first by Andrey Plekhanov with
LinOccult. His calculation shows a path 38 km more to the East
(perpendicular to the path) compared to Steve's prediction.
The probabilities to see a positive event are very small but nearly
equal for all observers inside the limits.
V-Magnitude of target star HIP 22157: 5.4 mag
Spectral Type: A0
Johnson B-V Colour Index: + 0.2
The max duration is expected to be 2.0 sec with a max drop of 12.7 mag.
The event will take place at an altitude of 54 deg and at azimuth 146
deg. The sun will be at an altitude of -10 deg. (At predicted centre
line for longitude E 05 deg).
There is a 1 sigma uncertainty interval of ± 15.6 path widths.
The probabilities to see a positive event:
Centre line: ~ 3 %
Path limits: ~ 3 %
1 sigma lines: ~ 2 %
2 sigma lines: ~ 1 %
(Calculation according to Raymond Dusser, E.A.O.N. Circular #10)
PLEASE REMEMBER: Predictions are sometimes wrong. Please observe even
with a small probability.
